Connector for printed circuit board

Abstract

In a connector A for a printed circuit board, the printed circuit board 3 is adapted to be held between and connected to a resilient contact piece 5 of each connection terminal 1, received in a terminal receiving chamber 13 of a connector housing 2, and a top plate portion 8 of the connection terminal 1 disposed in opposed relation to the resilient contact piece 5. A guide projection 16 to which the top plate portion 8 is adapted to be fitted is formed on an end wall 14a of the terminal receiving chamber 13 of the connector housing 2. The deformation of connection terminals attached to a connector housing can be prevented, thereby enabling a smooth, positive connection of the printed circuit board.

What is claimed is: 
     
       1. A connector for a printed circuit board, comprising: a connector housing having at least one terminal receiving chamber;   a connection terminal received in each said terminal receiving chamber, including a resilient contact piece and a top plate portion disposed in opposed relation to said resilient contact piece for holding said printed circuit board between said resilient contact piece and said top plate portion and eclectrically connecting a printed circuit on said board to said resilient contact piece; and   a guide projection formed on an end wall of each said terminal receiving chamber and projecting into said chamber, said top plate portion being fitted onto said guide projection.   
     
     
       2. The connector according to claim 1, wherein said connection terminal is a single integral member including said resilient contact piece and said top plate portion. 
     
     
       3. The connector according to claim 1, further comprising a flexible lock arm forward on a bottom wall of each said terminal receiving chamber for retaining said connection terminal in each said terminal receiving chamber when said top plate portion is fitted onto said guide projection. 
     
     
       4. A connector for a printed circuit board, comprising: a connector housing having at least one terminal receiving chamber;   a connection terminal received in each said terminal receiving chamber, including a resilient contact piece and a top plate portion disposed in opposed relation to said resilient contact piece for holding said printed circuit board between said resilient contact piece and said top plate portion and electrically connecting a printed circuit on said board to said resilient contact piece; and   a guide projecting formed on an end wall of each said terminal receiving chamber, said top plate portion being fitted onto said guide projection, wherein said top plate portion is tubular and rectangular in cross-section.   
     
     
       5. A connector for a printed circuit board, comprising: a connector housing having at least one terminal receiving chamber;   a connection terminal received in each said terminal receiving chamber, including a resilient contact piece and a top plate portion disposed in opposed relation to said resilient contact piece for holding said printed circuit board between said resilient contact piece and said top plate portion and eclectrically connecting a printed circuit on said board to said resilient contact piece; and   a guide projection formed on an end wall of each said terminal receiving chamber, said top plate portion being fitted onto said guide projection, wherein said guide projection has a semispherical distal end.   
     
     
       6. A connector for a printed circuit board, comprising: a connector housing having at least one terminal receiving chamber and insertion slits formed on one end portion thereof;   a connection terminal received in each said terminal receiving chamber, including a resilient contact piece and a top plate portion disposed in opposed relation to said resilient contact piece; and   first engaging means provided on said connector housing and projecting into said at least one chamber for engaging and correctly positioning said top plate relative to said insertion slits, wherein said printed circuit board inserted through said insertion slits is held between said resilient contact piece and said top plate portion positioned by said first means for an electrical connection.   
     
     
       7. The connector according to claim 6, further comprising: second means for retaining said connection terminal in each said terminal receiving chamber when said top plate is correctly positioned relative to said insertion slits. 
     
     
       8. A connector for a printed circuit board, comprising: a connector housing having at least one terminal receiving chamber and insertion slits formed on one end portion thereof;   a connection terminal received in each said terminal receiving chamber, including a resilient contact piece and a top plate portion disposed in opposed relation to said resilient contact piece; and   first means provided on said connector housing for correctly positioning said top plate relative to said insertion slits and for preventing complete insertion of said connection terminal into said terminal receiving chamber when said top plate portion is deformed more than a predetermined amount towards said resilient contact piece, wherein said printed circuit board inserted through said insertion slits is held between said resilient contact piece and said top plate portion positioned by said first means for electrical connection when said top plate portion is deformed less than said predetermined amount.
